"Unable to Validate your Application Error" While Uploading a new version of iOS App

Question

I have been trying to upload a new version for my ios App But I always end up receiving this error "UNABLE TO VALIDATE YOUR APPLICATION, "The application you have selected does not exist"

From Xcode Archiver. I followed this question here Xcode 6.4 The Application You Have Selected Does Not Exist

Which suggests to use Application Loader, After doing that I ended up getting bunch of errors such as these

ERROR ITMS-90049: "This bundle is invalid. The bundle identifier contains disallowed characters. [See the section of the Application Programming Guide entitled The Application Bundle.]" ERROR ITMS-90057: "Missing plist key. The Info.plist file is missing the required key: CFBundleShortVersionString." ERROR ITMS-90056: "This bundle is invalid. The Info.plist file is missing the required key: CFBundleVersion." The resulting API analysis file is too large.  We were unable to validate your API usage prior to delivery.  This is just an informational message. 

This errors dont make any sense since all the missing keys are already present in my app, along with appropriate bundle ID of my app which has been in the Appstore for an Year now.

Can anybody help me out regarding this,

I seemed to have tried all the solutions I could find, but to no avail, anybody else facing this? Is this another issue from apples server or maintenance side and I just have to wait a couple of hours before they fix it at thier end??

I was facing the same issue but then i used Application Loader and it worked for me. After validating your app Export your app by selecting option as Save for iOS App Store Deployment and then Just upload your apps ipa using Application Loader.
